Have you smartphone-flushed your toilet?

The Japanese, always at the forefront of innovative technology, now seem to have outdone themselves by devising a toilet that can be controlled by a smartphone.

Designed by the Japanese firm Lixil, the toilet goes on sale early next year, which can be operated by a smartphone application, one that also tracks user’s bowel movements.

The toilet uses Bluetooth to communicate with the mobile phone application.

It can then control all of the toilet’s functions, and even play music through speakers built in to the toilet’s base.

The application, which will be available for selected Android handsets, will work with three of the firm’s new range of lavatories.

Using the My Satis Android application, toilet users will be able to control the Bluetooth-equipped bathroom fitting with their smartphone, the Daily Mail reported.

Every feature, including flushing, lifting the toilet seat and sprays, can be controlled. Users can record their own preferred settings, and even play back music through the toilet’s speakers.

The system also records each use to monitor both water and electricity bills. It also has a health function which creates a diary for users to see how often they have used the toilet.
